Abstract

A handheld band saw includes a housing, a handle coupled to the housing and configured to be grasped by a user during a cutting operation, a motor supported by the housing, and a drive wheel assembly rotationally driven by the motor. The drive wheel assembly at least partially disposed within the housing. The band saw further includes a saw blade driven by the drive wheel assembly. The saw blade is configured to cut a workpiece during the cutting operation. The band saw further includes a pipe reamer attachment coupled to the drive wheel assembly. The pipe reamer attachment is configured to deburr the workpiece after completion of the cutting operation.

First claim

What is claimed is:

1. A handheld band saw comprising:
a housing;
a handle coupled to the housing and configured to be grasped by a user during a cutting operation;
a motor supported by the housing;
a drive wheel assembly rotationally driven by the motor, the drive wheel assembly at least partially disposed within the housing and including a drive wheel and a driven wheel;
a saw blade driven by the drive wheel assembly, the saw blade driveably disposed on an outer periphery of the driven wheel and the drive wheel and configured to cut a workpiece during the cutting operation; and
a pipe reamer attachment coupled to the drive wheel assembly, wherein the pipe reamer attachment is configured to deburr the workpiece after completion of the cutting operation,
wherein the pipe reamer attachment includes an annular shroud and a blade disposed within the annular shroud, and wherein the blade and the annular shroud co-rotate with the drive wheel assembly.

2. The handheld band saw of claim 1 , further comprising a battery removably coupled to the handle, wherein the battery, when coupled to the handle, is operably coupled to the motor and configured to provide power to the motor.

3. The handheld band saw of claim 2 , further comprising a trigger disposed adjacent a gripping portion of the handle, wherein power from the battery is supplied to the motor when the trigger is actuated.

4. The handheld band saw of claim 1 , wherein the motor defines a rotational axis, and wherein the pipe reamer attachment is rotationally driven by the motor about the rotational axis.

5. The handheld band saw of claim 1 , wherein the pipe reamer attachment is removably coupled to the drive wheel assembly.

6. The handheld band saw of claim 5 , further comprising a quick disconnect coupling that allows the pipe reamer attachment to disconnect from the drive wheel assembly by rotating the pipe reamer attachment in a first direction, and wherein the drive wheel assembly rotates in a second direction during the cutting operation that is opposite the first direction.

7. The handheld band saw of claim 1 , wherein the pipe reamer attachment is integrally formed with at least one component of the drive wheel assembly to form a single piece.

8. The handheld band saw of claim 1 , wherein the pipe reamer attachment is disposed on the drive wheel.

9. The handheld band saw of claim 1 , wherein the housing includes a deck and a guard coupled to the deck that cooperatively surround the saw blade in a shielded position, and wherein the deck and guard define a cut zone through which the saw blade passes in an exposed position to engage a workpiece.

10. The handheld band saw of claim 1 , wherein the motor defines a rotational axis, and wherein the drive wheel defines a drive wheel axis that is coaxial with the rotational axis.
